Blubox is a file compression and encryption software designed to help users safely compress graphic files. In order to evaluate it, you need to carefully read the registration release notes, as you need to complete a few steps before getting a key to unlock the program for the trial period. The first thing, after registration, is to create a new 'Blubox' file with a name of your choice. Then, you can add files to your archive. The process of adding file is a little bit slow, as the program reads and encodes each file while loading. I tested the program by adding JPEG images and BMP images to 'Blubox' files. In the first case, it took 5 minutes to add 197 JPEG files to a .blu file. The JPEG file were converted to BPM format. As for the BMP files, 197 files were added to a .blu archive in 18 minutes. While the addition of JPEGS was quite fast, during the addition of BMPs, the program froze a few times. After the files have been loaded up, you can preview them with some options (image flip, reverse, rotate, colors inversion, zoom in, zoom out) and you can print the out with high quality settings. The program also shows the general file properties, data elements, EXIF data and IPTC/file comments. Among the program options I must mention the image settings: you can choose the compression type and level; image preprocessing: you can force the bit depth and scale the images; you can choose to save JPEG images with a custom lossless compression level. One more thing: if you set the program to show real file icons, the operating speed of the program will be reduced dramatically, so it is recommendable to check this option only if you have a powerful machine.
